Cannot Authorize DLC by logging into alliance network
Can't login into Alliance network and consequently will not authorize ANY of the dlc I have
I have tried reparing/reinstalling as well as simply restarting my computer, origin or mas effect
OK, go
Scroll down to "DLC Patcher" and download the "" for ME3.
Unzip the RAR file and put both DLLs int your ">drive<:\Program Files (x86)\Origin Games\Mass Effect 3\Binaries\Win32" folder (override).
This will authorize the single player DLCs. I use this DLLs myself for my modded game but as always with third party software I have to tell you that you use this DLLs on your own risk.
